Apr 22, 2015 · Papers rarely included scatterplots, box plots, and histograms that allow readers to critically evaluate continuous data. Most papers presented continuous data in bar and line graphs. This is problematic, as many different data distributions can lead to the same bar or line graph. A histogram is a graph that represents the way numerical data is represented. The input to it is a numerical variable, which it separates into bins on the x-axis. This is a vector of numbers and can be a list or a DataFrame column. A higher bar represents more observations per bin. Also, the number of bins decides the shape of the histogram.
